Because most people are not sufficiently employed in themselves, they run about loose, hungering for employment, and satisfy themselves in various supererogatory occupations. The easiest of these occupations, which have all to do with making things already made, is the making of people: it is called the art of friendship.
Of 472 civilian occupations defined by the Department of Commerce, only six are majority immigrant (legal and illegal). These six occupations account for 1 percent of the total U.S. workforce. Many jobs often thought to be overwhelmingly done by immigrants are in fact majority native-born: 51 percent of maids are U.S.-born, as are 63 percent of butchers and meat processors, and 73 percent of janitors.
